Institutional access to convert self-custodied BTC directly into ETF shares just got a lot cheaper. BlackRock quietly cut IBIT's in-kind conversion minimum from $25 million to $1 million back in July, a 96% reduction, and told Bloomberg that over $5 billion in Bitcoin has already gone through the program. Bitwise went further, dropping its BITB threshold from $100 million down to $3 million (via an interim $50 million step).
For context: in-kind creation lets an eligible holder hand Bitcoin to an authorized participant, which then issues ETF shares directly rather than requiring the holder to sell BTC for cash, wire it, then rebuy exposure through the fund. This avoids execution costs and, depending on the holder's structure, may defer a taxable event. The SEC opened this door for crypto ETPs in July 2025.
Morgan Stanley and Galaxy have a similar referral setup, cutting their minimum from $25M to $5M and claiming onboarding times can shrink by up to 75%. Grayscale's in-kind creations jumped from 28% of gross volume in March to 62% in June. 21Shares saw average in-kind transactions around $5 million over three months.
BlackRock's Robbie Mitchnick pointed to rising physical risks tied to self-custody — kidnappings, home invasions, coercion — as one motivator, though the firm hasn't broken down the $5B by reason. Chainalysis and CertiK both recorded upticks in violent crypto-related incidents through mid-2026.
The flip side: US spot ETFs already hold roughly 5.9% of total BTC supply, and pushing more whales toward custodial ETF structures concentrates coins further with a small number of custodians, Coinbase chief among them, alongside ETF fees (0.25% for IBIT, 0.20% for BITB) that self-custody doesn't carry.
Does easier ETF conversion mark a meaningful shift away from self-custody among large holders, or is this still a rounding error against total BTC supply?
